INTRODUCTION

This article continues a series of publications that

for the first time considers the marine, brackish, and

freshwater ichthyofauna of Sakhalin Island. The first

part of Annotated List of Ichthyofauna of Inland and

Coastal Waters of Sakhalin Island (Dyldin and Orlov,

2021a) presented data on the history of taxonomic

studies of the ichthyofauna of Sakhalin Island, from

1809 to the present (2020), as well as brief geographi-

cal and oceanological characteristics of the area.

Information on 118 species of fish and lampreys from

4 classes (Petromyzonti, Elasmobranchii, Holoceph-

ali, and Actinopteri), 20 orders, 42 families, and

79 genera was presented. For 50 species, information

on collection specimens has been provided, including

five type species described from the waters of Sakha-

lin. The next two parts of Annotated List… (Dyldin

and Orlov, 2021b, 2021c) considered 284 species from

24 orders, 76 families, and 166 genera. For 206 spe-

cies, information on collection specimens has been

provided, including 39 type species.

This report provides information about 113 fish

species from 9 families (Triglidae, Hypoptychidae,

Gasterosteidae, Anoplopomatidae, Hexagrammidae,

Cottidae, Hemitripteridae, Psychrolutidae, and Ago-

nidae) and 53 genera, from three suborders (Scor-

paenoidei, Gasterosteoidei, and Cottoidei) of the

order Perciformes. Based on a collection specimen,

the species Malacocottus gibber is presented for the

first time for island waters.

The research methodology, abbreviations, and

environmental categories are given in the first part of

the work (Dyldin and Orlov, 2021a).

the mouth of the Lutoga River (Gudkov, 2010); south-

western coast to the northern part of the Tatar Strait

(Shuntov et al., 2014). Also, the closest records to the

island are from the southern part of the Sea of Okhotsk

247. Genus HYPOPTYCHUS Steindachner, 1880

404. Hypoptychus dybowskii Steindachner, 1880—

Korean sandeel. Northwest Pacific. Sakhalin: south-

eastern and western parts, including Aniva and Terp-

eniya bays (Schmidt, 1904, 1950; Taranetz, 1937a;

Lindberg, 1959; Ueno, 1971; Lindberg and Krasyu-

kova, 1975; Shuntov et al., 2014; Dyldin and Orlov,

2017; Dyldin et al., 2018, 2020; Orrell, 2020). Marine,

brackish water. Common. Non-commercial.

S a m p l e s: ZIN RAS: No. 12600—Korsakov,

Khlomsk [Maoka], Tatar Strait, Sea of Japan, south-

western Sakhalin; USNM No. 51494—Khlomsk

Conservation status: IUCN (Data Defi-

cient).

121. Fam ily GASTEROSTEIDAE Bonaparte,

1831 —S ti ckleback s

248. Genus GASTEROSTEUS Linnaeus, 1758

405. Gasterosteus aculeatus Linnaeus, 1758—

Three-spined stickleback. North Atlantic, North

Pacific and adjacent Arctic. Sakhalin: probably only

the northwestern part (Pietsch et al., 2012; Dyldin and

Orlov, 2017; Dyldin et al., 2020). Euryhaline species;

inhabits sea and fresh waters. It forms anadromous,

estuarine, and freshwater forms. Common. It is not a

commercial species in the waters of Sakhalin.

N o t e s. On Sakhalin, the three-spined stickleback

remains poorly studied. It should be noted that in the

work of Pietsch et al. (2012), the distribution of this

species within the island is limited to the northwestern

part, and for the other parts, including the northern

one, Gasterosteus sp. is indicated. However, at present,

the latter should be classified as the recently described

species G. nipponicus Higuchi, Sakai et Goto, 2014.

G. aculeatus has a complex polymorphic structure,

and therefore Russian authors usually consider the

three-spined stickleback within the framework of the

complex species, G. aculeatus complex (Berg, 1949;

Zyuganov, 1991; Bugaev, 2007). Notes on the taxo-

nomic position and distribution of G. aculeatus in the

inland waters are presented in our earlier works (Dyl-

din and Orlov, 2017; Petukhova et al., 2019; Dyldin

et al., 2020).

C o n s e r v a t i o n s t a t u s: IUCN (Least Con-

cern).

406. Gasterosteus nipponicus Higuchi, Sakai et

Goto, 2014—Japanese three-spined stickleback.

Northwest Pacific. Sakhalin: southern, western, and

northern parts (Higuchi et al., 2014; Dyldin and Orlov,

2017; Dyldin et al., 2018; Petukhova et al., 2019; Dyl-

din et al., 2020; Kawai, 2020). Anadromous, forms

estuarine resident forms (Higuchi et al., 2014; Arai

et al., 2020). Numerous. Non-commercial.

S a m p l e s: HUMZ: Nos. 140390−140399—

Severnyi Bay lagoon, north Sakhalin; Nos. 183229–

183238—Aynskaya River estuary, southwestern

Sakhalin.

Conservation status: IUCN (Not Evalu-

ated).

249. Genus PUNGITIUS Coste, 1848

407. Pungitius polyakovi Shedko, Shedko et

Pietsch, 2005—Polyakov’s ninespine stickleback. An

endemic species of the southeastern part of Sakhalin

Island; inhabits small rivers flowing into lakes Svobo-

dinsky and Russkoe, the system of Vavayskoye-Chi-

bisan lakes, and Busse lagoon (Shedko et al., 2005;

Pietsch et al., 2012; Dyldin and Orlov, 2017). Freshwa-

ter. Common in a limited area. Non-commercial.

N o t e s. Described in the waters of the southeast-

ern part of Sakhalin: type locality: 46°47.035′ N,

143°47.337′ E, Puzin Peninsula, Sakhalin Island, Russia.

S a m p l e s: ZIN RAS: No. 53441 (holotype),

No. 53442 (paratypes)—46°47.035′ N 143°47.337′ E,

source of the stream flowing from the Khvalisekoe

Lake into the Russkoe Lake, Puzin Peninsula, Sakhalin.

Conservation status: IUCN (Near

Threatened).

408. Pungitius pungitius (Linnaeus, 1758)—Nine-

spine stickleback. Europe, Asia, and North America.

Sakhalin: along all coasts, where it is represented by

both lacustrine-riverine and semi-anadromous forms

(Nikolskii, 1889; Berg, 1949; Taranetz, 1937a; Niki-

forov et al., 1987; Zyuganov, 1991; Pietsch et al., 2001,

2012; Safronov and Nikiforov, 2003; Safronov et al.,

2008; Labai et al., 2015). Anadromous, freshwater

(forms residential forms). Common. Non-commer-

cial.

N o t e s. Previously (Berg, 1949; Schmidt, 1950

(partly); Nikolskii, 1956; Lindberg and Legeza, 1965;

Keivany and Nelson, 2000), the species was believed

to be replaced by the subspecies P. pungitius sinensis

(Guichenot, 1869) and P. pungitius tymensis (Nikol-

skii, 1889) in the southern part of the Sea of Okhotsk

(including the entire Sakhalin Island) and in the Sea of

Japan. Allocation of separate species P. sinensis and

P. t y m e n s i s (Bogutskaya and Naseka, 2004; Boguts-

fauna of Sakhalin, and the above cited features of its

distribution on the island should be attributed to

P. s in e n s i s or P. t ym e n s i s . Representatives of the genus

Pungitius within Sakhalin are poorly studied. Notes on

the taxonomic position and distribution of P. pungitius

in the island waters are presented in our earlier works

(Dyldin and Orlov, 2017; Dyldin et al., 2020).

Conservation status: IUCN (Least Con-

409. Pungitius sinensis (Guichenot, 1869)—Chi-

nese ninespine stickleback. Northwest Pacific. Sakha-

lin: along all coasts (Berg, 1949; Schmidt, 1950; Lind-

berg, 1959; Lindberg and Legeza, 1965; Nikiforov

et al., 1987, 1997; Zyuganov, 1991; Pietsch et al., 2001,

2012; Safronov and Nikiforov, 2003; Safronov et al.,

2008; Nikitin et al., 2014; Labai et al., 2015; Dyldin

and Orlov, 2017; Dyldin et al., 2018, 2020; Kawai,

2020; Orrell, 2020; UWFC, 2020). Anadromous;

freshwater and brackish water. Common. Non-com-

mercial.

N o t e s. Previously, a number of researchers

(Berg, 1949; Schmidt, 1950; Nikolskii, 195 6; Lindberg

and Legeza, 1965; Pietsch et al., 2001) considered the

Chinese nine-spined stickleback as a subspecies of

P. p. s i n e n s i s .

commercial.

N o t e s. The species was described by Nikolskii

(1889) from specimens (syntypes) taken from small

freshwater lakes of the Tym River estuary, northeast-

ern Sakhalin (type locality: small lakes in the Tym

River estuary, north-eastern Sakhalin, Russia). In the

past (Lindberg and Legeza, 1965; Nikiforov et al.,

1997), it was considered a subspecies of P. p u n g i t i u s

tymensis.

2014; Tuponogov and Kodolov, 2014; Orlova et al.,

2019). Marine. Rare. In more northern waters of Rus-

sia (southeastern Kamchatka, the continental slope of

the western part of the Bering Sea, and Northern Kuril

Islands), it forms commercial agglomerations,

although is caught mainly as a by-catch (Tokranov and

Tuponogov and Kodolov, 2014). It is also known from

the Sea of Okhotsk waters of Siretoko Peninsula, Hok-

kaido, Japan (Uchida, 2020). Marine. Rare. Due to its

rare occurrence, it has no commercial value in Russian

waters (Orlov and Tokranov, 2003); however, it is

occasionally harvested by Russian longliners in the

area of the Emperor Seamounts (Orlov et al., 2012;

N o t e s. Previously, in some works (Rutenberg,

1962; Ueno, 1971; Lindberg and Krasyukova, 1987) it

was attributed to the genus Agrammus. According to

other data (Quast, 1964; Parin et al., 2002, 2014), the

latter is synonymized with the genus Hexagrammos.

Numerous. In the southwestern part of the island,

including the coastal waters of Moneron Island, forms

pre-spawning aggregations (Dyldin et al., 2020).

Commercial.

N o t e s. Some authors (Mecklenburg et al., 2002;

Mecklenburg and Eschmeyer, 2003) considered the

species as a junior synonym or subspecies of the north-

ern atka makerel, P. monopterygius (Pallas, 1810). Sub-

sequently, based on molecular studies (Crow et al.,

2004), the status of an independent species was

restored.

Moneron Island (Solomatov et al., 2009). It is also

recorded in the adjacent southern waters of the Sea of

Okhotsk of Hokkaido (Kawai, 2020; Uchida, 2020).

Marine. Rare. In the Pacific waters of the Kuril

Islands and eastern Kamchatka, it is an important

object of domestic fishery (Antonov et al., 2016; Orlov

and Frenkel’, 2019).

N o t e s. Schmidt (1904) indicated this species for

the southwestern coast of Sakhalin near Kholmsk

[Mauka] with a reference to a specimen from the ZIN

collection (No. 12522, one specimen, 1901, collector

P.Yu. Schmidt). However, at that time, the southern

Okhotsk atka mackerel P. azo nus Jordan et Metz, 1913,

(Fadeev, 2005; Calabuig, 2014; Kawai, 2020; Uchida,

2020), which does not exclude its findings off the Sea

of Okhotsk coast of Sakhalin. Marine. Not abundant.

It is caught as a by-catch in the fishery for other scul-

pins.

Notes. Alcichthys alcicornis (Herzenstein, 1890),

considered as a valid species by some authors

(Sokolovskii et al., 2011), however, is recognized by

others (Lindberg and Krasyukova, 1987; Panchenko

et al., 2011; Parin et al., 2014; Tuponogov and Kod-

olov, 2014) as a junior synonym for A. elongatus. Pre-

viously, the species was attributed to the genus Elo-

phichthys (Lindberg, 1959) or Pseudoblennius

(Schmidt, 1904).

of the Sea of Okhotsk, Hokkaido (Inagawa and Yabe,

2006). Marine. Rare. Non-commercial.

N o t e s. The species was described by V.K. Solda-

tov (1922) from specimens (syntypes) obtained in the

Tatar Strait off the mainland coast and eastern Sakha-

lin (Cape Bellingshausen and Cape Terpeniya, Sea of

Okhotsk). Subsequently, Neelov (1979) selected a lec-

totype based on a specimen (ZIN RAS No. 20613,

male) from the waters of the mainland part of the

Tatar Strait, near Cape Khoy. Previously, the species

was noted for Aniva Bay and the southern part of the

Sea of Okhotsk, Schmidt (1904, partly) under the

name A. pacificus Gilbert, 1896, and later (Schmidt,

1927, 1950; Ueno, 1971), as A. miacanthus Gilbert et

Burke, 1912. Later A. aporosus and A. miacanthus were

shown to be independent species (Neelov, 1979). At

present, A. pacificus and A. miacanthus are not

included in the list of ichthyofauna of Sakhalin, since

they are distributed much further north, in the Bering

Sea and near the northern Kuril Islands (Orlov, 1998;

eva et al. (2006b), with a reference to which it was later

indicated by Parin et al. (2014). Marine. Probably, to

confirm its presence in island waters, it is necessary to

carry out a comparative morphological analysis of the

samples with the data of the original description.

N o t e s. Is poorly studied and is usually listed only

for off Funakawa, Akita Prefecture, Japan (Watanabe,

(Schmidt, 1927, 1950; Taranetz 1937a; Isii, 1940;

N o t e s. The species was described by Soldatov

(1915) based on samples from Aniva Bay and the Tatar

Strait: type locality by lectotype—Aniva Bay, southern

Sakhalin Island, Russia. Then, a lectotype was

described on a copy from Aniva Bay (ZIN RAS 12190,

male) (Neelov, 1979; Lindberg and Krasyukova,

1987). Some authors (Taranetz, 1937a; Schmidt,

1950; Neelov, 1979; Nakabo, 2002; Sideleva et al.,

2006b) consider this taxon as a subspecies A. dydymovi

schmidti, others (Lindberg and Krasyukova, 1987;

Parin et al., 2002, 2014), as an independent species

A. schmidti. In our previous works (Dyldin and Orlov,

2017; Dyldin et al., 2018, 2020), due to the insignifi-

cant morphological differences of this species from

A. dydymovi (see Schmidt, 1950), it is marked with a

N o t e s. The finding of a closely related species

A. leprops Bolin, 1936 (Tsugaru sculpin) in the south-

ern part of the Sea of Okhotsk near Hokkaido and the

possibility of the species finding in Aniva Bay, south-

was based on a sample from the NSMT-P collection

N o t e s. Now it is known, that the typical habitat

for this species is Aniva Bay (Kai and Nakabo, 2009):

C. gonez Schmidt in Jordan et Starks (not ex Schmidt),

1904a. P. 298, Fig. 29 (type locality by lectotype:

Aniva Bay, Sakhalin Island, Russia). Earlier (Neelov,

1979; Lindberg and Krasyukova, 1987), the lectotype

was determined from other samples collected by

Schmidt (1904) in Peter the Great Bay and preserved

by him at ZIN RAS (ZIN RAS No. 12742). Neverthe-

less, the description of this species in the work of

Schmidt (1904) according to the priority rule of ICZN

(2020) should be considered a junior synonym for his

description, published a little earlier in the work of

Jordan and Starks (1904a), and therefore the author-

ship of the original description should belong to

Schmidt, but not to Jordan and Starks. The latter used

part of the description (text) and 5 samples (CAS-SU

No. 7713—Aniva Bay) got from Schmidt, that is

directly indicated by the authors (Jordan and Starks,

1904a., P. 298–299). Also they attribute the author-

ship of the species to Schmidt. This also applies

directly to the authorship of the generic name Cottius-

culus Schmidt, 1904 in Jordan et Starks, 1904, which,

in their opinion, belongs to Schmidt, which corre-

sponds to sect. 50.1. ICZN (2020).

2009—Japan Sea sculpin. Northwest Pacific. Mainly

in the Sea of Japan off the coast of the Japanese islands

of Hokkaido, Honshu, and Kyushu, as well as the

Korea Peninsula (Kai and Nakabo, 2009). Sakhalin:

Aniva Bay (Kai and Nakabo, 2009). Marine. Abun-

433. * Cottiusculus schmidti Jordan et Starks,

1904—Kinkazan Island sculpin. Northwest Pacific.

Pacific side of northern Honshu in the Tohoku region

of Fukushima and Miyagi prefectures (Kai and

Nakabo, 2009). Recorded in the Sea of Okhotsk

waters adjacent to Sakhalin from the side of the island

Hokkaido, Japan (Kawai, 2020; Uchida, 2020), which

does not exclude its presence in Aniva Bay (Dyldin

et al., 2018). Marine. The presence needs clarification.

Non-commercial.

N o t e s. Kai and Nakabo (2009), based on a revi-

sion of the genus Cottiusculus, all C. schmidti speci-

mens previously indicated for the Far Eastern waters

of Russia assigned to the new species C. nihonkaiensis,

and the distribution of C. schmidti was limited by a

type habitat in the Pacific waters of northern Honshu

in the Tohoku region. Nevertheless, under the name

C. schmidti, the species is listed for the Sea of Okhotsk

coast of Hokkaido, Japan (Uchida, 2020) and is repre-

sented in numerous specimens (more than 300) in the

HUMZ collection (Kawai, 2020). It should also be

noted that Kai and Nakabo (2009) did not use collec-

tion material from the HUMZ collection for compar-

ative studies. Thus, this species may be recorded in the

waters of southern Sakhalin, including Aniva Bay

(Dyldin et al., 2018).

et al. (2014). Also, the closest findings to the island

were recorded in the waters of northern Japan (Hok-

kaido and northern Honshu), the Southern Kuril

Islands (Shikotan Island), and the Korea Peninsula

(Pietsch et al., 2001; Shedko, 2002; Chereshnev, 2003;

requires clarification. Non-commercial.

N o t e s. The presence of this species in the south-

ern part of Sakhalin requires documentary confirma-

tion. In the past, C. nozawae was synonymized with

C. amblystomopsis Schmidt, 1904 or C. pollux Gün-

ther, 1873 (Berg, 1949; Watanabe, 1960). Later, on the

basis of its ecological features, genetic data, and taking

into account reproductive isolation, it was restored as

an independent species (Goto, 1980, 1983; Okumura

northern part, including Schmidt Peninsula and rivers

flowing into the Amur Estuary (Taranetz, 1937b, as

C. poecilopus; Sideleva et al., 2006b, as C. poecilopus;

UWFC, 2020). Freshwater, brackish water (Amur

estuary). Limited by the northern part of the island.

Non-commercial.

N o t e s. Berg (1949), and later Nikolskii (1956)

considered C. szanaga as a synonym for C. poecilopus

Heckel, 1837. Moreover, the area of the latter within

Eurasia covered a vast territory, from Europe (the Vis-

tula River basin) to the Amur basin. Currently, the sta-

tus of C. szanaga has been restored to an independent

species (Shedko and Shedko, 2003; Kottelat, 2006;

Bogutskaya et al., 2008; Sideleva and Goto, 2009;

Goto et al., 2015), and the distribution of C. poecilopus

is limited to the waters of Europe.

sculpin. Northwest Pacific, Bering Sea and adjacent

Arctic. Sakhalin: along all coasts, including Aniva,

Terpeniya, and Sakhalin bays, as well as waters of

Moneron Island and the Amur estuary (Jordan and

Starks, 1904a; Schmidt, 1904, 1950; Tanaka 1908;

brackish water. Common. In the southern part of

Sakhalin, it forms commercial agglomerations

(Panchenko and Pushchina, 2019). It is caught as a by-

catch with subsequent processing for fish-f lour

(Sokolovskii et al., 2011).

N o t e s. Previously (Jordan and Starks, 1904a;

Tanaka, 1908; Isii, 1940; Lindbergh, 1959) for Aniva

Bay and the southern part of Sakhalin Island, another

species, Ceratocottus namiyei Jordan et Starks, 1904

(Namiye’s sculpin) or subspecies Enophrys diceraus

namiyei, was also indicated. The latter is considered

synonymous with E. diceraus (Neelov, 1979; Tokranov

and Sheiko, 2009; Parin et al., 2014). Other data based

on moleculargenetic and karyological analyses sug-

gests that E. namiyei is a valid species (Moreva et al.,

limited to the northern part of the Sea of Okhotsk, the

Pacific side of the northern Kuril Islands, eastern

Kamchatka, and the Bering Sea (Parin et al., 2002,

2014; Tokranov and Orlov, 2012; Balanov and Mat-

veev, 2018). To the south was recorded up to the south

part of Kuril Islands and in the Sea of Okhotsk waters

of Hokkaido (Mecklenburg et al., 2016, 2018), which

is probably a mistake. In the past, the range of this spe-

cies included the Sea of Japan up to Peter the Great

Bay, including the southern part of Sakhalin

(Schmidt, 1904; Nakabo, 2002; Tuponogov and Kod-

olov, 2014). Marine. It is considered as a promising

commercial object (Orlov, 2007, 2011).

Mecklenburg et al., 2016, 2018); Aniva Bay, southern

part of the Sea of Okhotsk (Schmidt, 1904). Marine.

Rare. It has no commercial value in the waters of

Sakhalin due to the rare abundance. In areas with a

high abundance, it is considered as a promising com-

mercial object (Orlov, 2007, 2011).

N o t e s. Schmidt (1904) believed that Aniva Bay

and other parts of Sakhalin Island are inhabited by

H. hemilepidotus (Tilesius, 1811), and H. jordani is

only a variation of it. Therefore all lord fish in this area

were indicated under the same name H. hemilepidotus.

Subsequently, Schmidt (1950) indicated H. jordani as

a subspecies H. hemilepidotus jordani for the studied

area. A number of samples from ZIN RAS (Nos. 12221,

12244, 12858, 12859, and 12983), mentioned in his

work (Schmidt, 1904, as H. hemilepidotus) for the

waters of the island, were later redefined as another

species, H. gilberti (Sideleva et al., 2006a). According

to some researchers (Parin et al., 2014), H. jordani is

distributed much farther north, from the northern part

of the Sea of Okhotsk. Nevertheless, recent works

(Mecklenburg et al., 2016, 2018) note a preserved

specimen of this species, taken in the waters of eastern

Sakhalin in 2003.

S a m p l e s: ZIN RAS ? No. 12219 (possibly lost, it

on the Sea of Okhotsk side, from the Amur estuary to

Aniva Bay, including Sakhalinskiy, Baikal, Nyisky,

Piltun, and Terpeniya bays, as well as the Nevelsky

Strait in the northern part of the Tatar Strait (Schmidt,

1904, 1950; Soldatov and Lindber g, 1930; Isii, 1940;

mainly in the northeastern part up to Terpeniya Bay. It

is used as a secondary f ishing object (with processing

into fodder meal), but it is considered promising com-

mercial target (Orlov, 2007, 2011).

N o t e s. Previoulsy, it was attributed to the genus

Melletes, later (Parin et al., 2014; Mecklenburg and

Steinke, 2015; Mecklenburg et al., 2016, 2018), it was

shown that the genus Melletes is a junior synonym of

the genus Hemilepidotus.

N o t e s. Taranetz (1936) described this species by

one (holotype) specimen from the central part of the

Sea of Okhotsk near Iony Island. Later, the species

was also found on the Pacific side of Hokkaido

(Japan), in the central and northern parts of the Kuril

Islands, and near Kamchatka (Yabe et al., 1983;

Fedorov et al., 2003; Sideleva et al., 2006a). The pres-

ence of this species on the Sea of Okhostk side of

Sakhalin requires confirmation by the stored samples,

be noted that for descriptions the I. s. bispinis and

I. u. crassus samples (syntypes) from the northern part

of Sakhalin, Sea of Okhotsk have been used. Accord-

ing to (Mecklenburg et al., 2016, 2018), it is likely that

I. spatula includes several species; morphogenetic revi-

sion is required throughout the habitat of this species.

N o t e s. This species is often indicated as a subspe-

cies M. platycephalus taeniopterus or Myoxocephalus

platycephalus taeniopterus or is synonymized with

Megalocottus platycephalus (Pallas, 1814) (Berg, 1949;

Andriyashev, 1954; Lindberg and Krasyukova, 1987;

Mecklenburg et al. 2002, 2016, 2018; Sokolovskii

According to other data (Bogutskaya et al., 2008;

Parin et al., 2014; Dyldin and Orlov, 2017; Dyldin

et al., 2018, 2020), it is recognized as a valid species.

According to Gudkov (2006), the taxon M. taeniop-

terus from Sakhalin includes several species (or sub-

species), as the populations of this species from differ-

ent habitats differ significantly in a number of biolog-

ical and ecological characteristics. At the same time,

two species previously described by Tanaka (Tanaka,

1908) from the southern part of Sakhalin, Porocottus

nigrescens Tanaka, 1908 (type locality: southern

Sakhalin Island, western Sea of Okhotsk, Russia) and

P. i j i m a i Tanaka, 1908 (type locality: mouth of the

Susuya River, southern Sakhalin Island, Russia) are

possibly valid species that are currently considered

synonymous with M. taeniopterus (Parin et al., 2014).

head sculpin. North Pacific. Sakhalin: eastern and

western parts (Tuponogov and Kodolov, 2014;

UWFC, 2020). According to some data (Fedorov

et al., 2003), the species is widespread throughout the

Sea of Okhotsk. However there are documental

records only for the Sea of Okhotsk side of Iturup

Island, Southern Kuril Islands (UWFC, 2020).

Marine. The abundance off the coast of Sakhalin

requires clarification. Non-commercial.

N o t e s. The presence of this species within

Sakhalin area requires documentary evidence. In the

past, Schmidt (1904), on the basis of morphometric

studies, suggested that this species is most likely a syn-

onym for M. stelleri. Neelov (1979), on the basis of

morphology and biology, placed this species in the

subgenus Littocottus, allocated by him.

Okhotsk sculpin. Northwest Pacific. The closest

record to the island was documented on the mainland

of the Sea of Okhotsk in Catherine Bay, Sakhalinskiy

Bay (Sideleva et al., 2006a). It is common in the

northern part of the Sea of Okhotsk from the Shantar

Islands (Schmidt, 1950; Neelov, 1979; Sheiko and

Fedorov, 2000; Fedorov et al., 2003; Napazakov,

2008; Parin et al., 2014). Marine.

N o t e s. Andriyashev (1937), when comparing the

meristic characters of this species and M. verrucosus

(Bean, 1881), did not find differences between them

and proposed to consider M. ochotensis in synonymy

with M. verrucosus.

N o t e s. Taranetz (1937a) allocated a special sub-

species M. polyacanthocephalus ensiger (Jordan et

Starks, 1904) from the Sea of Okhotsk and the north-

ern part of Japan. However, later (Schmidt, 1950) it is

given as a separate species M. ensiger. Later Neelov

(1979) synonymized this species with M. polyacantho-

cephalus.

N o t e s. Previously, some authors referred to the

island waters under the name M. raninus Jordan et

Starks, 1904 (Tanaka, 1908; Isii, 1940). The latter is

now considered synonymous with M. stelleri (Parin

et al., 2014; Dyldin and Orlov, 2017). Taranetz (1937a)

pointed to the existence of two forms of Steller’s scul-

pin: southern, from the Sea of Japan and northern

from the Sea of Okhotsk and the Bering Sea. However,

he considered the southern form as a subspecies of

M. stelleri decastrensis (Kner, 1865).

southern part (Tanaka, 1908; Jordan et al., 1913;

Nakabo, 2002); southeastern and southwestern parts

(Ueno, 1971). The closest records to the island also

were documented in the waters of Hokkaido in the

Kunashir Strait (Shinohara et al., 2012; Nakae and

Shinohara, 2020). Marine. The presence in Sakhalin

waters requires documentary confirmation. Non-

commercial.

N o t e s. The species presence in the island waters

was first reported by Tanaka (1908), but the label of

the studied sample did not contain information about

the location of its capture. Later, Snyder (Snyder,

1912), examined the description of Tanaka (1908) and

concluded that his description did not correspond to

the diagnostic key of O. maschalis, as well as to another

closely related species Ocynectes modestus Snyder,

1911. Namely, the difference in rays in the dorsal (D)

and anal (A) fins: D 17 v er sus 13–14 a n d A 14 versus

10–11 in O. maschalis and O. modestus. Thus, this spe-

cies has never been documented for Sakhalin waters,

and early indications of this species by a number of

authors for the south of Sakhalin (Jordan et al., 1913;

Ueno, 1971; Masuda et al., 1984, as O. modestus;

Nakabo, 2002; Parin et al., 2014; Kim et al., 2015)

should be recognized as erroneous.

477. Taurocottus bergii Soldatov et Pavlenko,

1915—Berg’s sculpin. Northwest Pacific. Sakhalin:

southeastern and southwestern parts, including the

waters of Moneron Island (Lindberg, 1959; Ueno,

1971; Parin et al., 2002, 2014; Sideleva et al., 2006a;

Shuntov et al., 2014; Kim Sen Tok and Kim, 2019;

Dyldin et al., 2020); perhaps, in Aniva Bay (Dyldin

et al., 2018). Marine. Not abundant. Non-commer-

cial.

N o t e s. Described by Soldatov and Pavlenko

(1915) by samples (syntypes) from the adjacent waters

of the Tatar Strait: type locality—Tatar Strait,

47°55′00′′ N 139°39′30′′ E, Russia. Spelling the spe-

cies name as “bergi” is erroneous (Fricke et al., 2020).
